... quantiles, for example, for 0.8, are higher than for proportional fair and round-robin scheduling. In terms of fairness, it is remarkable that the shape of the curves for Round-robin and proportional-fair are ... compare user and system throughput for round-robin, Max C/I, and proportional fair scheduling. The results show that on the one hand, as expected the two channel-...
